Joel Liu's List: Startup lessons

    • Wow - this is amazing.

      Right this very moment (well, a few moments ago when I wasn't procrastinating on HN) I was in the midst of extracting data from a client's old website in preparation of creating a new website.

      A lot of that data is contained within images.

      From a few preliminary tests, I'm hugely impressed. This seems on-par with any other OCR software I've used, and the fact that it happens in realtime in the browser is amazing.

      I tried it on a piece of content I'd just had to type out, that was originally in an image. Typing out the content took about 10 minutes. Copying and pasting with Naptha, and then making some minor edits/corrections, did the same thing in about 2 minutes.

    • To a certain extent, of course. The 2% was based on the assumption that if you are benchmarking against re-typing, you expect the same kind of quality you'd get from having a good typist re-typing the documents.

      From my own experiments, I tend to find that you can read through and correct errors only relatively marginally faster than you can type because you either follow along with the cursor or need to be able to position the cursor very quickly when you find an error, and as the error rate increases, trying to position the cursor to each error very quickly gets too slow.

      Dropping accuracy in your effort to correct the text doesn't really seem to speed things up much. You likely speed it up if you're willing to assume that anything that passes the spellchecker is ok (but it won't be, especially as modern OCR's often try to rely on data about sequences of letters, or dictionaries, when they're uncertain about characters)
